Description

Technical Field

[0001] The utility model relates to the technical field of terminals, in particular to a waterproof plug-in terminal. Background Art

[0002] Terminals are components that connect batteries to external conductors. In electrical engineering, terminals mostly refer to wiring terminals, also called wiring terminals. They are classified into single-hole, double-hole, sockets, hooks, etc. They are classified by materials such as silver-plated copper, zinc-plated copper, copper, aluminum, iron, etc. Their main function is to transmit electrical signals or conduct electricity.

[0003] A Chinese patent discloses a waterproof plug-in terminal (authorization announcement number CN219717295U). This patented technology can make the plug-in ring more and more tightly attached to the sealing gasket during threaded connection by installing a sealing gasket and cooperating with an oblique structure. The deeper plug-in groove can greatly increase the connection area between the plug-in ring and the sealing gasket. After the terminal connection is completed, a closed structure from top to bottom can be automatically formed at the outer end of the terminal. After water flows directly onto the terminal, the water can flow down along the closed hood-shaped structure to avoid water intrusion. In combination with the threaded connection structure, the waterproof effect of the plug-in terminal is further improved.

[0004] With respect to the above and existing related technologies, the inventors believe that the following defects often exist: the existing waterproof plug terminals have complicated operation steps during installation and removal, and cannot be installed and removed quickly, thereby affecting the work efficiency of users.

At the same time, the above-mentioned arrangement also facilitates the user to quickly install the first terminal 1 and the second terminal 2. The operation is simple and convenient, and the structure is stable. By setting the first through hole 12, when the user presses the pressing plate 11 to drive the control rod 10 to move inside the lower shell 6, it is convenient to limit the position of the moving direction of the control rod 10. By setting the structure of the slide bar 13 and the second through hole 14, the movement trajectory of the transmission plate 9 is prevented from being offset, thereby improving the stability of the device. By setting the adjusting groove 15, the slider 8 is assisted in moving during the movement process. By setting the pressure spring Spring 16, when the user pushes the control rod 10 to drive the transmission plate 9 to make the slider 8 disengage from the inside of the slide groove 7, the pressure spring 16 begins to compress, and when the position of the first terminal 1 and the second terminal 2 needs to be fixed, the resilience of the pressure spring 16 is used to drive the transmission plate 9 to push the slider 8 into the inside of the slide groove 7, and by arranging the connecting head 17 and the connecting groove 18 structure at the top and bottom of the first terminal 1 and the second terminal 2, when the first terminal 1 and the second terminal 2 are installed, by inserting the connecting head 17 into the inside of the connecting groove 18, it is not easy for water vapor to enter the inside of the second terminal 2, thereby avoiding the situation where the circuit is damp, and by arranging the sealing gasket 21 at the top and bottom of the first terminal 1 and the second terminal 2, the first terminal 1 and the second terminal 2 are tightly attached to the surface of the sealing gasket 21 when installed, thereby further improving the sealing performance of the device.
